Bulova 1968 Date King

I recently got this watch and I'm trying to figure out whatever I can about it like the year is it, jewels, the model it is and such like that can anyone help please The face says Bulova and it is wind set and wind up mechanical. It says "T SWISS T" on the bottom of the face. The hands illuminate in the dark and has the date display. It runs very good and strong. The back casing says BULOVA stainless steel case shock resistant waterproof anti-magnetic 36938 M68. The inside case says 2519. The movement says 11BLCD, 17 jewels, unadjusted swiss MD, BZW. The band says Speidel on every link. Any help would be greatly appreciated!

Wow is that good or bad??? It clearly says M68 on the caseback as you can see. I posted pics of the watch back, face, and movement earlier so you all could view. When you say the caseback shouldmatch the movement within a year what do you mean, like how can you tell the year, what numbers or writing are you looking at? So how should I go about finding out more about my watch? I went to 2 vintage jewelers and neither had seen a watch like mine but said they are positive its 100% real.
